Specification of Letters Patent.

Patented May 6, 1919.

Application filed December 1, 1917. Serial No. 204,934.

To all whom it may concern:

Be it known that I, ROY D. Jnrrnrns, a citizen of the United States,residing at Granada, in the county of Martin and State of Minnesota,have invented new and useful Improvements in Dust caps for Hubs, of

' which the following is a specification.

, wheel without necessitating the use of tools,

or fastening elements to maintain theband operatively associated withsaid parts.

The nature and advantages of the invention will be better understoodwhen the following detail description is read in connection with theaccompanying drawing, the

invention residing in the construction, combination and arrangement ofparts as claimed.

In the drawing forming a part of this specification like numerals ofreference indicate similar parts in the several views and wherein IFigure 1 is a sectional view taken through a wheel hub showin the deviceforming the subject matter of my invention associated therewith and withthe spindle. v

M Fig. 2 is a detail view of the band.

, Referring more particularly to the drawing in detail A indicatesgenerally the spindle provided with the usual shoul-' der B and conebearing C, while the hub of the wheel is indicated generally at 'D andincludes an annular exteriorly disposed flan e E. I o Tl me protectorforming the-subject matter of my invention is in the nature of apressedmetal cup which -is provided with a central opening 10 ofsuitable dimensions and snugly receives the spindle A, while the centerportion of the protector is depressed as at 11 to accommodate theshoulder B against which the center portion of the protector bears,partly embracing the latter as clearly shown in Fig. 1. The protector isfurther formed to provide an annular flange 12 which is concentricallydisposed about the adjacent end of the hub D, snugly contacting thelatter to prevent dirt and other foreign matter from gaining access intothe hub of the wheel. The protector is rendered more effective for thispurpose by reason of the fact that the flangebears against the flange E-on the hub. The flange 12 defines with the wall 13 of the depression 11,a

groove 14 which is adapted to receive an annulus .of suitable-packing15, so that when the protector is mounted upon the spindle.

as shown in Fig. 1 the packing 15 not only prohibits the admittance ofdirt and other foreign matter into the hub of the wheel, but also servesto space the hub from the protector, and maintain the lubricant in aclean fresh condition. A protector constructed in'accordance with myinvention may be readily and easily associated with the spindle withoutnecessitating the use of tools. In this. connection it will be notedthat the protector as hereinabove stated rests against the shoulder B ofthe spindle partly embracing the latter, and when the cone bearing C isplaced upon the spindle in its operative position, it serves to maintainthe protector in its operative position, "thus eliminating the necessityfor use of additional fastening means.

While it is believed :that' from the foregoing description the natureand advantages of the invention will be readily apparent, I desire tohave it understood that the same is merely illustrative of the preferredembodiment of the invention, which I do not consider restrictive,inasmuch as such changes may be resorted to when desired as fall'withinthe scope of what is claimed.

What is claimed is A dust cap for use on a motor vehicle stub axle, saidcap having a circumferential flange to engage around the inner end of awheel hub and also having a conical recessed portion to receive theshoulder of the axle and an inwardly-extending annular flange at thesmaller end of the depressed circum ferential flange being such as tocause an annular chamber to be formed between the wheel hub and the cupfor the reception of packing. Y t v In testimony whereof I aflix my s1ature.
